Title: Dental camera device
Inventor: IGA KENICHI
IPC: A61C19/04
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a small and easy-to-handle dental camera device which can take pictures of an area inside the oral cavity for diagnosis easily without skill and without much burden on a patient, and can be seen easily by a patient by performing observation inside the oral cavity with a nonflexible barlike optical waveguide. SOLUTION: A nonflexible bar as an optical waveguide 3 is attached at this CCD camera main body 1, and an objective lens 4 is mounted on top of the optical waveguide 3. Pictures taken by the optical waveguide 3 are shown on a monitor 8. Compared with a traditional dental camera with which observation is based on a mirror, operation of this camera device for observation for diagnosis is easier, and the total size of the camera device can be made smaller because of the narrow and small optical waveguide 3. And this camera device doesn't have restrictions on operation including, for example, avoidance of blocking between the mirror and the lens of the camera, as a traditional dental camera has, so this camera device is easier to be handled in a general way.

Title: Split type optical head
Inventor: KAMISADA TOSHIMASA
IPC: G11B7/135
Filed: 1988-08-30
Abstract: PURPOSE:To eliminate the deviation of a ray caused by the tilt of a moving part and to reduce the offset of a servo signal by selecting a distance between a mirror of the movable part and an objective lens principal point so as to be nearly twice the focal distance of the lens. CONSTITUTION:A movable case 6 is moved in a radial direction of an optical disk 8 and placed on a prescribed track of the optical disk 8. When the movable case 6 is not tilted, the ray 11 is made incident perpendicularly on the optical disk through the axis 12 and the light reflected in the optical disk 8 traces the same path as the incident light. When the movable case 6 is tilted by a minute angle theta, the point of the ray 11 passing through an objective lens 9 moves from a point A to a point C and the focal point on the optical disk 8 moves from a point B to a point B'. When the distance between a mirror 7 and a principal point of the objective lens 9 is selected to be twice the focal distance (f), the ray 11 is made incident perpendicularly onto the optical disk 8 along a path CB'. Thus, the reflected light from the optical disk 8 traces the same path as the incident light and no deviation is caused, then the production of an offset of the servo signal is prevented.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To secure both a large heat generation quantity and durability by setting a coefficient of thermal expansion of a structural member of a heat generation chamber larger than that of a rotor in a housing. SOLUTION: A front plate 2 and a rear plate 3 forming a heat generation chamber 6 is formed of aluminum dicast having a coefficient of linear thermal expansion of 2.10×10<-5> (1/K). A rotor 11 is formed of a medium carbon steel having a coefficient of linear thermal expansion of 1.17×10<-5> (1/K). After starting a viscous heater, when heat is generated in the silicon oil by continuous operation and temperature rises, since a coefficient of linear thermal expansion of the front plate 2 and the rear plate 3 is larger than that of the rotor 11, the front plate 2 and the rear plate 3 are expanded by heat larger than the rotor 11. In this viscous heater with this structure, a liquid tight space is not reduced, and interference and abrasion is not generated between the front plate 2, the rear plate 3 and the rotor 11, and both of calorific value and durability are secured.

Title: Band separation interleave repeater device
Inventor: NASU SEIICHI
IPC: H04B7/155
Filed: 1984-10-11
Abstract: PURPOSE:To prevent the degradation of the amplification quantity of a high frequency amplifier and the transmission of unnecessary high frequency signals due to cross modulation by switching the connection to a filter part in the cycle of a high frequency signal transmission time from a receiving antenna to a transmitting antenna to lead only the signal having a frequency corresponding to an input signal to the high frequency amplifier. CONSTITUTION:If the first high frequency input signal f1IN is received by a receiving antenna 1 when an input point 4a and an output point 4b are connected, a BPF5 permits only the input signal f1IN to pass through, and it is transmitted as the first high frequency output signal f1OUT from a transmitting antenna 3 after a high frequency signal transmission time tau(mus). A switch means 4 performs the switching operation to connect the point 4a to an output point 4c when the time tau(mus) elapses after the input signal f1IN is received, and as the result, an isolation high frequency signal F1 is stopped by a BPF6 and is not transmitted to a directional coupler 7. By the switching operation at intervals of the time tau(mus), the input signal f1IN is transmitted as the output signal f1OUT from the transmitting antenna 3 at intervals of the time tau(mus) without influences of the isolation high frequency signal F1.

Title: Processing method for copper foil for printed circuit
Inventor: HINO EIJI
IPC: C23C18/32
Filed: 1990-08-14
Abstract: PURPOSE:To provide various characteristics equivalent particularly to a Cu-Ni treating and to eliminate a decrease in heat resistant peeling strength when acrylic adhesive is used by roughing the surface of a copper foil with plating made of copper and cobalt, and then forming a cobalt plating layer or a plating layer made of cobalt and nickel. CONSTITUTION:In order to improve peeling strength of a copper foil after laminating, roughing is conducted by a copper-cobalt alloy plating. A cobalt-or cobalt-nickel-plating thereon must be conducted in the degree of not substantially reducing adhering strength of the foil to a board to be very thin, thereby performing a desired effect. Thereafter, it is rust prevented as required. The foil has heat resistant peeling strength, antioxidative and hydrochloric acid resistance equivalent to those of the case of Cu-Ni treating, a printed circuit having 150mum of pitch circuit width or less can be etched with CuCl2 etchant, and alkali-etched. It has black similar to that in the case of Cu-Ni treating, and is important in view of high alignment accuracy and heat absorption ratio.

Abstract: PURPOSE:To obtain powdery oligosaccharide, economically in an industrial scale, by carrying out the chromatographic separation, concentration, drying, and recovery successively in respective specific methods. CONSTITUTION:A pseudo-moving bed is formed in a bed filled with a cation exchange material, by circulating a fluid through a bed in a manner to form an adsorption zone, a refining zone, a desorption zone and a concentration zone from the upstream- side to the downstream side, and shifting the positions of the feeding zone and the extraction zone of the liquid intermittently toward downstream-side. An aqueous solution containing maltose and an oligosaccharide is passed through said pseudo- moving bed under the following conditions. The ratio (phi2) of the volume flow rate to the apparent volume flow rate of the cation exchange material in the refining zone is controlled to 0.3-0.5, and the ratio (phi4) in the concentration zone is controlled to 0.3-0.6. The solution is separated into the adsorbed maltose solution and the non- adsorbed oligosaccharide solution continuously by the above chromatographic process. The aqueous solution of the oligosaccharide is made to contact with hot air in the form of mist in a drying chamber furnished with an atomizer, a hot-air inlet, and an air outlet, and is pulverized. The powder of the oligosaccharide is separated from the exhaust discharged from the drying chamber.
